Which Reflector to Buy?

Hi all;

Which reflector would give the best coverage over an area of 4x4x7? and I will be using a 600w MH/HPS.

Cool Tube
Euro Reflector
Diamond Reflector
Megalux V Reflector
Adjust a Wings Reflector

Thanks.

Hm, it looks like I am in the same boat as you. I have a room thats 5x4x8 and will be going with a 600w HPS and the Euro reflector, I believe. I cant find much information on it, but it looks like the best value for your money. Its totally sealed, has the 6" vent holes, and looks pretty solid. I would be interested to see what anyone else has to say.

the euro reflector is kinda smallish, its not that wide, i use easycool 6's and they are bigger than the euros, but still they are small, i use mine for 3x3 or 3x4, so do yourself a favor and try to find something with a larger footprint air cooled preferably

Just searched the net and came across this Air-cooled reflector, what do ya think of this?

Air-cooled Cool-Star Reflector

I should have said, ill be doing 12-16 Auto's.

That looks cool.. I actually like the look of the EasyCool 6 that morrisgreenberg suggested: http://www.htgsupply.com/viewoption.asp?ID=377. Its only about $13 more than the Euro reflector and about 4.5" wider.

Any of the Sun System reflectors are really good. Same with the Hydrofarm reflectors. Most people find the Cool Sun relfector about optimum as far as coverage, spread, and heat disappation. Just stick with a 6" duct hole though. Once you get into the 8" category, a lot more light is going out that hole and not down on your plants. One of the local hydro shops had on display a 400W MH using the Magnum reflector (huge), and if you're doing a sog operation would probably work really well too. Just be aware of size and weight, and whether or not you plan to put them on movers or not.
